Deformable Slice-to-Volume Registration for Motion Correction of Fetal Body and Placenta MRI
Alena Uus,Tong Zhang,Laurence H. Jackson,Thomas A. Roberts,Mary A. Rutherford,Joseph V. Hajnal,Maria Deprez +6 more
TL;DR: A Deformable SVR (DSVR), a novel approach for non-rigid motion correction of fetal MRI based on a hierarchical deformable S VR scheme to allow high resolution reconstruction of the fetal body and placenta is proposed.
Book ChapterDOI
Deformable Slice-to-Volume Registration for Reconstruction of Quantitative T2* Placental and Fetal MRI.
Alena Uus,Johannes K. Steinweg,Alison Ho,Laurence H. Jackson,Joseph V. Hajnal,Mary A. Rutherford,Maria Deprez,Jana Hutter +7 more
TL;DR: This work introduces a novel pipeline for motion correction in 4D T2* and 3D T 2*+T2 placental MRI datasets based on the deformable slice-to-volume registration (DSVR) method.
Journal ArticleDOI
Multi-channel 4D parametrized Atlas of Macro- and Microstructural Neonatal Brain Development
Alena Uus,Irina Grigorescu,Maximilian Pietsch,Dafnis Batalle,Dafnis Batalle,Daan Christiaens,Daan Christiaens,Emer Hughes,Jana Hutter,Lucilio Cordero Grande,Lucilio Cordero Grande,Anthony N. Price,Jacques-Donald Tournier,Mary A. Rutherford,Serena J. Counsell,Joseph V. Hajnal,A. David Edwards,Maria Deprez +17 more
TL;DR: In this article, a multi-channel (MC) continuous spatio-temporal parametrized atlas of the brain development that combines multiple MRI-derived parameters in the same anatomical space is presented.
Book ChapterDOI
Multi-channel Registration for Diffusion MRI: Longitudinal Analysis for the Neonatal Brain
Alena Uus,Maximilian Pietsch,Irina Grigorescu,Daan Christiaens,Jacques-Donald Tournier,Lucilio Cordero Grande,Jana Hutter,David Edwards,Joseph V. Hajnal,Maria Deprez +9 more
TL;DR: The pipeline for registration of multi-shell high angular resolution diffusion imaging (HARDI) is extended with a novel similarity metric based on angular correlation and an option for multi-channel registration that allows incorporation of structural MRI.
Book ChapterDOI
Spatio-Temporal Atlas of Normal Fetal Craniofacial Feature Development and CNN-Based Ocular Biometry for Motion-Corrected Fetal MRI
Alena Uus,Jacqueline Matthew,Irina Grigorescu,Samuel Jupp,Lucilio Cordero Grande,Anthony N. Price,Emer Hughes,Prachi A. Patkee,Vanessa Kyriakopoulou,Robert Wright,Thomas A. Roberts,Jana Hutter,Maximilian Pietsch,Joseph V. Hajnal,A. David Edwards,Mary A. Rutherford,Maria Deprez +16 more
TL;DR: In this article, the authors presented the first spatio-temporal atlas of the fetal head that includes cranio-facial features and covers 21 to 36 weeks gestational age range.
